This evergreen plant has many branches. The size and general morphology of the plant vary significantly from one plant to another.
Mostly, the plant looks like a shrub and does not grow more than 2 meters in height. However, in some cases, it grows well above that and looks like a small tree.
The leaves are ovate and opposite with length up to 15 cm. The tip is pointed. Breaking the leaf or branch produces a white sap.
The size of the flowers also varies. It can be from 2.5 to 5 cm across. The white petals are five in number with a slight twist towards the left (idampiri in Malayalam), making the flower appear like a pinwheel. There is also a variety with the twist towards the right (valampiri), but I think it is rare.
There is also another variety of Nandyarvattam with fragrant double-flowers. Whereas the normal variety is not fragrant.
The fruit is about 3 cm long while the seed has a length of 7.5 mm.
Nandyarvattam is native to south and southeast Asia including India and parts of China where it has several uses in traditional medicines. The plant prefers moist, fertile soil with good availability of sunlight although it can grow under shade too.
Cultivation is possible from seeds as well as stem cutting.
